ORE-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 400,601, dated April 2,1889. Application filed March 17, 1888. Serial No. 267,495. (No model.)

of which the following is a full,clear`, and ex-F act description.

My invention relates to an improvement in ore-Crushers, and has for itsobject to provide an apparatus upon the principle of a Chilean mill,which will be simple, durable, economical, and eifective in operation;

The invention consists in the construction and combination of theseveral novel features of the apparatus, as will be hereinafter fullyset forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure l is a plan view of the device. Fig. 2 is a central verticalsection taken partially on line @c aa of Fig. 1. Figs. 3 and 4 are`detail views of the shovels. Figs. 5 and 6 are detail viewsrepresenting, respectively, the mode of journaling the Crushers and thesuspension of the off-take pipe.

In carrying out the invention, A represents a frame consisting of spacedtop and bot tom plates, a and a', held a suitable distance apart byperpendicular posts, standards, or

pillars a2, and a preferably-cylindrical upwardly-projecting iiange, b,secured to the upper surface of the top plate, a, forming anorereceptacle, B, which receptacle is providedv with a false detachablebottom, b. A vertical shaft, D, is journaled in bearings integral withthe upper and lower plates, and the -upper end of said shaft is enlargedand bifurcated, as shown at d in Figs. 1 and 2. At or near the lower endof the shaft a horizontal pulley, d', is keyed, which pulley is beltedto any convenient drive-shaft. A series of aligning apertures isprovided in the lupper members of the shaft, and to the outer faces ofthe said members a horizontal arm, D', is secured, from which armsperpendicular spaced rods e project downward to within a short distanceof the bottom of the receptacle B. The upper ends 'ofi the rods e,passing through the arms D', are reduced` and threaded and adj ustablyheld in connection with the said arms by Ineans of set-nuts, asillustrated in Figs. 3 and 4. Above the arms Dl and below the nuts oneend of a horizontal plate, E, is held in engagement with the rods, andthe said plates, while adjustable, are preferably set to have aninclination in direction of the shaft D. I To the lower ends of the rodse shovels E are attached, the outer ends whereof are adjustablyconnected to the plate E by an apertured vertical plate,`E2, attached tothe shovels and extending through the arms, held at the desiredelevation by a pin, e. The purpose of the shovels is to carry thecrushed ore from the sides of the receptacle B to the center and deliverthe same to an aperture, C, in the false bottom of the said receptacleat or near the center, as illustrated in Fig. 2. To facilitate thisdelivery one inner shovel is curved inward at the toe, as shown indetail, Fig. 4, and as applied in Fig. 2.

A spout, 7c, is made to surround an aperture -in theplat'e a, whichaperture registers with the delivery-aperture C in the receptacle B, andat each side of said spout lugs k are attached to the upper plate, a,and

links or chains k2 connect the said lugs with the upper end of adelivery pipe or chute, K, at which upper end an elbow is providedadapted to surround the spout 7c, as shown in Figs. 2 and 6. Thedelivery-pipe is further supported by av chain, 7c3, secured to theupper plate at one end.

A bolt, 71., preferably projects through the lower aligning apertures inthe upper bifurcated ends of the shaft D, and upon said bolt the innerflattened ends of independent axles H I-I are made to rest side by side,the said axles extending outward in opposite directions. The saidflattened ends of the axles are provided with vertical elongated slots7L', and the said axles are pivoted between the members of the shaft Dby a bolt or threaded pin, 71,2, passing through the members and theslots in the axles. The bolts h and h2 are each retained in position bya suitable nut and nut-lock.

Upon the outer ends of the axles H and H weighty cylindricalcrushing-rollers H2 and H3 are held to revolve, traveling within thereceptacle B. It will be observed that by reason of the separate axlesthe said rollers IOO are entirely independent one of the othe r, andthat by reason of their peculiar attachment to the shaft D, shouldeither roller meet with an obstruction, they have sufficient verticalplay to override the same Without retarding or interfering With themovement of the opposite roller.

The material to be crushed is preferably fed, in any suitable manner,into a hopper, R, built upon one outer side of the receptacle B, havingdirect communication therewith.

The false bottom b may be replaced when Worn out by another, and ittakes the Wear from the plate a, which forms the permanent bot-tom ofthe receptacle B.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with the ore-receptacle and the vertical shaftbifurcated at its upper end, o f the axles H, overlapped at their innerends and having vertical aligned slots h', the bolt h2, passed throughthe said bifurcated end and slots, a second bolt, h, below the bolt h',and on which the under sides of the slotted ends of the axles rest, andthe crushing-rollers on said axles, substantially as set forth.

2. The combination, With the ore-receptacle, the crushing-rollers, andtheir operati 11g-shaft, of a horizontal arm, D', projecting from thesaid shaft, a plate, E, secured to the said arm at au an gle thereto,the vertical rod e, de-

pending from arm D', the shovel on the lower end of said rod and havinga vertical plate, E2, extending up through the plate E and securedthereto, substantially as set forth.

3. The combination, with the ore-receptacle, the vertical shaft, and thecrushing-rollers, of the horizontal arms D', projecting from said shaftbetween the rollers, the vertical spaced rods e, having shovels on theirlower ends and extending at their upper ends through the arms D', theslotted plates E, adjustable horizontally on said upper ends, and theapertured vertical plates E2, extending from the shovels up through theslots in plates E, and the securing-pins e', substantially as set forth.

4. The combination, with a receptacle having an open top andoutlet-aperture, a spout therefor, a chute suspended from the bottom ofthe receptacle, engaging the spout, a vertical shaft journaled in thereceptacle, provided with a bifurcated upper end, and crushing-rollersprovided With independent axles pivoted in the bifurcated shaft end, ofopposing horizontal arms secured to the shaft between the rollers, andadjustable shovels carried by said arms, adapted to follow the rollers,substantially as and for the purpose specilied.
